Title: Control-driving device for elevator
Inventor: AOKI KENICHI
IPC: B66B5/02
Filed: 1989-07-20
Abstract: PURPOSE:To decide the start-up direction and travel speed of a cage at the time of recall operation being commanded for some reason by providing a device for detecting the door opening zone of a recall floor and the minimum number of memory-type position detecting switches. CONSTITUTION:When a recall button 24 is operated and a recall command is inputted into a microcomputer 20 at the time of fire breaking out or the like, first of all, whether a cage is at the door opening zone of a recall floor (for instance, the third floor) is judged by the input from a proximity switch 13. If the cage is within the door opening zone of the recall floor, there is no need for recall operation, and the door is opened to allow the proceeding to a program in the following stage. If the cage is not within the door opening zone of the recall floor, the on-off state of a position detecting switch 17 is checked. If the switch 17 is off, that means the cage is positioned higher than the switch, and the cage is therefore driven downward in the start-up direction and at high speed.

Filed: 1986-08-14
Abstract: PURPOSE:To reduce an electrode area and to improve recording and reproducing capacity, etc., by controlling the connection of a divided electrode and common 3rd electrode by a conductivity imparting means. CONSTITUTION:The recording of an information signal to a pyroelectric material layer 2 is executed by impressing a prescribed voltage to the 2nd electrode 3 of a recording medium 1 and the 3rd electrode 5 disposed annularly to the outer periphery of the disk-shaped recording medium 1 and irradiating a photoconductor 4 formed in continuation with the one divided electrode DP(k) corresponding to the region of the pyroelectric material layer 2 to be recorded by using the conductivity imparting means B. The photoconductor 4 is imparted with the conductivity by such irradiation; therefore, the one divided electrode DP(k) is short circuited and is electrically connected to the 3rd electrode 5. The change of the polarization state arises and the recording is executed when the pyroelectric material layer 2 is heated by using a heating means A at this time. The characteristics such as high-speed writing, high-speed reading out and increase of the current of a leading out signal to large current are improved by such division of the electrodes.

Title: Device for restricting output for hydraulic power plant
Inventor: UMEZAWA SOHEI
IPC: H02P9/04
Filed: 1985-08-28
Abstract: PURPOSE:To use a generator fully to the limit of an authorized output without reducing the capacity factor by opening and closing a flow regulating valve based on only the output value of a water-turbine speed governing device when the output of said generator is lower than said authorized output. CONSTITUTION:The detected signal of the output of a generator 1 from an output detecting device 2, is compared with the set value of an output reference value setting device 4 which is set at an authorized output, by a comparator 5. Also, difference between the detected signal and the set value is integrated by a differential integrator 7. The output value of a water-turbine speed governing device 8 is subtracted from the output value of this differential integrator 7 by a subtractor 9. The output value of this subtractor 9 controls a flow regulating valve via a flow-regulating valve driving device 10, to lower the increase in the output of the generator 1 down to the authorized output value. When the output of the generator 1 is lower than the set value, the contact 6'' of a relay is operated by the output signal of the comparator 5, to cut off the output signal of the differential integrator 7.

Title: Driving method of ink jet head
Inventor: ISHII HIROSHI
IPC: B41J2/045
Filed: 1981-11-28
Abstract: PURPOSE:To elevate the printing accuracy with a less effect of interference vibration by applying voltage pulses to an ink gun for injecting ink and the ink gun adapted to refuse the injection of a part or the whole of ink at the same timing with a different waveform in the opposite direction to each other. CONSTITUTION:When a drive voltage pulse is applied to a piezo electric element 8, a pulse is applied to a piezo-electric element 8' in the opposite direction to the drive voltage pulse with a lower voltage to reduce the pressure variation in an ink gun 4 to such an extent as to at least keep the meniscus of a nozzle 6 from breaking. In other words, as soon as a drive pulse 12 is applied to the piezo-electric element 8, a non-drive pulse 13 is done to the piezo-electric element 8'. The pressure inside an ink gun 2 forms a waveform 14 but the pressure change in the ink gun 4 reduces as shown by the waveform 15 because the effect of the piezo-electric element 8' can be cancelled by the effect of the piezo- electric element 8. This never allows the pressure change to overcome the surface tension of the ink in the nozzle 6 and thus the meniscus only oscillates but it kept from breaking.

Abstract: PURPOSE:To reduce the size of a recording device and to lower the price by providing a beam splitter between a recording medium and a scanning means and splitting laser light from the scanning means into a recording beam and a detection beam for a laser beam spot position on the recording medium. CONSTITUTION:A laser beam deflected by a rotary polygon mirror 5 passes through a convergent lens 6 to travel to the recording medium 7, but it is split by the beam splitter 16 such as a half-mirror provided between the convergent lens 6 and recording medium 7 into the recording laser beam 17 and detection laser beam 18; the detection laser beam 18 passes through an encoder 12 and a lens 13 and is converged to a photoelectric converting element 14 and the recording laser beam 17, on the other hand, is illuminated to the recording medium 7. Therefore, even when recording is not performed, the laser beam is passed by an optical modulator 2 to some extent, and consequently the position where the recording medium is irradiated with the laser beam is detected.
